未定义的变量：$ _SESSION Laravel

I have problem when get PHP superglobal variable $_SESSION from inside laravel controller.

I can get Moodle session from laravel. I can get moodle session in laravel with $_SESSION['USER'] using this example, but if I run php artisan route:list it returns an error, like this:

So I cannot use the Laravel redirect function. Can anyone help me with this? Is there any other way to call the superglobal $_SESSION in the Laravel controller? Thank you

You can use session functions provided by laravel

Save something on session variable

 Session::put('name', 'yourname');

Retrieve

Session::get('name')

Unset

Session::forget('name');
